I found a 'new' 1999 Yamaha 6hp, 2stroke 2 cyl.

I am turning my back on the 'new' Mercury / Thoatsu / Nissan 6hp 4 stroke I just purchased.... it is simply not as good of a motor for our boats then the Yamaha.

I like the (slightly) less fuel use, but the vibration, power, weight, are not living up to my expectations.


The fuel use (in real numbers) between my old (identical) Yamaha 2 stroke and the 4 stroke show only a slight savings... the 2 stroke did speeds at less then 1/3 throttle that I need 3/4 throttle on the 4 stroke to get (I have tried 2 different props).


Anyway, just another data point for the discussion.
